What's wrong?
The air disc brake caliper on the 2019-2020 Newmar Ventana, Ventana Le, Essex, London Aire, Kountry Star, and Mountain Aire motorhomes is the clamp that presses the brake pads against the brake rotor. Its mounting bolts hold the caliper tight to the brake anchor plate, so braking force goes into slowing the motorhome instead of moving the caliper.
On these motorhomes, the caliper mounting bolts were not tightened enough during chassis assembly. Without enough clamping force, the bolts can loosen and let the caliper shift against the anchor plate. That movement reduces brake effectiveness, which means the motorhome needs more distance to slow or stop and increases crash risk.
There is no warning sign before failure. An authorized Daimler Trucks North America service facility inspects the caliper mounting bolts and repairs the brake assembly as needed.

What happens at the repair

The inspection and any required repair are free under the recall. If you already paid out of pocket for this brake caliper bolt repair before the recall work, Newmar's standard reimbursement plan covers documented expenses.

Frequently asked questions
What is recall 20V171?
Recall 20V171 covers 129 2019-2020 Newmar motorhomes with brake caliper mounting bolts that were not tightened enough on DTNA chassis. Loose caliper bolts can reduce brake effectiveness and increase crash risk. DTNA dealers will inspect and repair the vehicles for free.
What should I do if my 2019-2020 Newmar motorhome is on this recall?
Check your VIN to confirm your specific motorhome is included in recall 20V171. If it is, contact a DTNA dealer or Newmar customer service to arrange the inspection and repair. Reference NHTSA campaign 20V171 when you call. The repair is free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and Newmar says DTNA dealers will inspect and repair the affected vehicles free of charge. Parts and labor are covered for this recall repair.
What is the safety risk?
The risk is reduced braking performance. If the brake caliper mounting bolts loosen, the brakes lose effectiveness and crash risk increases. Confirm your VIN, then arrange the free inspection and repair through a DTNA dealer before relying on the motorhome for travel.
What if I bought my Newmar motorhome used?
The free recall repair still applies. Recall coverage follows the vehicle, not the first owner. If you bought the motorhome used or never received a letter, check your VIN to confirm whether your specific Essex, London Aire, Kountry Star, Mountain Aire, Ventana, or Ventana Le is included.
